Nursing Elites

1. When a client with a history of atrial fibrillation is admitted with a new onset of confusion, which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is an Electrocardiogram (ECG). When a client with a history of atrial fibrillation presents with new-onset confusion, an ECG is crucial to assess for cardiac ischemia, which could be a potential cause of the confusion. A chest X-ray (Choice B) is not typically the first-line diagnostic test for evaluating confusion in a client with atrial fibrillation. Arterial blood gases (ABGs) (Choice C) are more useful in assessing oxygenation and acid-base balance rather than the cause of confusion in this scenario. While an echocardiogram (Choice D) provides valuable information about cardiac structure and function, it is usually not the initial diagnostic test needed in the evaluation of acute confusion in a client with atrial fibrillation.

2. After checking the fingerstick glucose at 1630, what action should be implemented?

• A. Notify the healthcare provider.
• B. Administer 8 units of insulin aspart SubQ.
• C. Give an IV bolus of Dextrose 50% 50 ml.
• D. Perform quality control on the glucometer.

Correct answer: B

Rationale: Administering insulin aspart (rapid-acting insulin) is the appropriate action to manage the elevated glucose level of 1630. Choice A, notifying the healthcare provider, is not the immediate action needed for this glucose level. Choice C, giving an IV bolus of Dextrose 50%, would exacerbate hyperglycemia instead of treating it. Choice D, performing quality control on the glucometer, is not relevant to the management of the patient's glucose level at this time.

3. A client is admitted for cellulitis surrounding an insect bite on the lower right arm, and intravenous (IV) antibiotic therapy is prescribed. Which action should the nurse implement before performing venipuncture?

• A. Lower the right arm below the level of the heart.
• B. Elevate the right arm on a pillow.
• C. Apply a tourniquet above the insertion site.
• D. Apply a warm compress to the insertion site.

Correct answer: A

Rationale: Before performing venipuncture for IV therapy, the nurse should lower the right arm below the level of the heart. Lowering the arm helps dilate the veins, making it easier to locate and access a suitable vein for the procedure. Elevating the arm on a pillow, applying a tourniquet above the insertion site, or applying a warm compress to the insertion site are not appropriate actions before venipuncture as they can affect the venous blood flow and make the procedure more challenging.

4. A client with chronic heart failure is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?

• A. Serum potassium of 3.0 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 1.5 mg/dl
• D. Blood glucose of 200 mg/dl

Correct answer: A

Rationale: A serum potassium level of 3.0 mEq/L requires immediate intervention in a client receiving furosemide. Furosemide can cause potassium loss, leading to hypokalemia, which can be dangerous, especially in patients with heart failure. Hypokalemia can predispose the client to cardiac dysrhythmias, weakness, and other complications. Therefore, prompt intervention is necessary to prevent these adverse effects. Choice B (Serum sodium of 135 mEq/L) is within the normal range and does not require immediate intervention. Choice C (Serum creatinine of 1.5 mg/dl) may indicate kidney dysfunction but does not pose an immediate threat to the client's safety. Choice D (Blood glucose of 200 mg/dl) may suggest hyperglycemia, which is important but not as urgent as addressing hypokalemia in a client with heart failure receiving furosemide.

5. The mother of an adolescent tells the clinic nurse, 'My son has athlete's foot. I have been applying triple antibiotic ointment for two days, but there has been no improvement.' What instruction should the nurse provide?

• A. Antibiotics take two weeks to become effective against fungal infections like athlete's foot.
• B. Continue using the ointment for a full week, even after the symptoms disappear.
• C. Applying too much ointment can reduce its effectiveness. Apply a thin layer to prevent maceration.
• D. Stop using the ointment and encourage complete drying of the feet and wearing clean socks.

Correct answer: D

Rationale: The correct answer is D. Athlete's foot (tinea pedis) is a fungal infection, not a bacterial infection that would respond to antibiotics. The primary management involves keeping the feet well-ventilated, dry after bathing, and wearing clean socks to prevent moisture buildup, which promotes fungal growth. Using an antibiotic ointment like triple antibiotic ointment is not effective for treating athlete's foot. Therefore, the nurse should advise the mother to stop using the antibiotic ointment and focus on promoting proper foot hygiene to manage the fungal infection. Choices A, B, and C are incorrect as they do not address the fungal nature of athlete's foot and the ineffectiveness of antibiotic ointments in its treatment.
